Coded bitstream unit structure.
A bitstream unit the smallest element of a bitstream which is meaningful on its own. For example, an H.264 NAL unit.
See the codec-specific header for the meaning of this for any particular codec.
| CodedBitstreamUnitType CodedBitstreamUnit::type |
Codec-specific type of this unit.

| uint8_t* CodedBitstreamUnit::data |
Pointer to the directly-parsable bitstream form of this unit.
May be NULL if the unit currently only exists in decomposed form.

| size_t CodedBitstreamUnit::data_size |
The number of bytes in the bitstream (including any padding bits in the final byte).

| size_t CodedBitstreamUnit::data_bit_padding |
The number of bits which should be ignored in the final byte.
This supports non-byte-aligned bitstreams.

| AVBufferRef* CodedBitstreamUnit::data_ref |
A reference to the buffer containing data.
Must be set if data is not NULL.

| void* CodedBitstreamUnit::content |
Pointer to the decomposed form of this unit.
The type of this structure depends on both the codec and the type of this unit. May be NULL if the unit only exists in bitstream form.
